It is anticipated this will lead to the technologies being developed at full-scale in the years ahead.
Mocean’s technology ‘Blue Horizon’ is a floating hinged structure; while AWS has developed a fully-submerged point absorber named the ‘Archimedes Waveswing’.
Commenting on the awards Tim Hurst, Managing Director of Wave Energy Scotland, said, “These state-of-the art designs represent the most advanced, and innovative devices in the UK today, and our program is ensuring that Scotland stays front and center of the global wave energy story.
“This funding will allow both companies to further develop their designs before building and testing the prototypes in Orkney in 2020, where marine engineering expertise is plentiful.”
The winning designs were selected following assessment using Wave Energy Scotland’s ‘stage gate’ selection process which assessed the most promising concepts before they proceeded to the next funding stage.
Over the course of four years eight original Wave Energy Converter (WEC) concepts were narrowed down to four. The two winning projects were then selected after a rigorous assessment procedure where Wave Energy Scotland staff and independent external experts worked through a wide set of criteria to evaluate each submission.
The Scottish Government established Wave Energy Scotland in 2014 with the goal of establishing a wave energy industry in Scotland and has since provided more than £30 million to develop commercially available wave energy technologies and sub-systems.
Paul Wheelhouse, Minister for Energy, Connectivity and the Islands, said, “With 465,000 square kilometres of seas in Scotland’s Exclusive Economic Zone, Scotland’s capacity to generate wave power is very considerable indeed and wave energy devices represent real game-changers for the industry not only here in Scotland but on a global scale. I very much look forward to seeing the progress of both devices in the coming months.”
Contractors from other work strands in the overall WES program have already begun collaborating with the WEC designers to achieve improved performance, as well as inform possible solutions in the areas of structural materials, control systems and power take-off.
